All,
I thought this important enough to break out of the owners thread.
If you have a 420/520 series machine the embedded controller apparently works a little different. The old version of tpfancontrol works, however it has glitches.
Troubadix has posted a newer version that seems to eliminate many of these glitches. Follow the thread in these two locations:

His website hasn't been updated with the new version yet:
